英文摘要The fine structure constant a can be extracted from high-precision spectroscopy of the 2(3)P(J) fine structure splittings in helium and light helium-like ions. In this work, the 23PJ fine structure splittings of helium and Li+ ion are calculated, including relativistic and QED corrections of order m alpha(4), m alpha(4) (m/M), m alpha(5), m alpha(5) (m/M), and Douglas-Kroll operators of m alpha(6) and m alpha(6) (m/M), which provide an independent verification for the previous calculations performed by Drake [Can. J. Phys. 80 1195 (2002)] and by Pachucki and Yerokhin [Phys. Rev. A 79 062516 (2009); Phys. Rev. Lett. 104 070403 (2010); Can. J. Phys. 89 1139 (2011)]. The results of the three groups agree with each other.
